We summarise a recent study looking at top quark polarisation effects in charged Higgs boson production. Lab frame angular and energy observables relating to leptonic decays of top quarks are analysed, and corresponding asymmetry parameters obtained. These are shown to be sensitive to top polarisation and robust with respect to higher order corrections. Thus, they are an efficient probe of charged Higgs parameter space.
